6. Photography has the power to move usPhotographs can grab our attention and speak directly to our emotions. Nick Ut’s photograph of a crying Vietnamese girl whose clothes have been burnt away by napalm embodies the power of a single image. At a more subtle level, we can learn lessons about a whole range of emotions. Grief has the power to wash away the luminance and chrominance of our lives. There is no magic way to restore them at will. We have to be patient. But while waiting we can search for the shapes and patterns that are still there in the greyness. They will lead us back to colour eventually. At moments of great sorrow in my life, I have used images to express that hope of returning a colour.

Photography, at its best, is a powerful language which speaks to our emotions. It allows us to tell our story and show others our framing of the world around us.
